I don't think I have ever seen a scope mounted so far back, but that should not make a difference. Are the rings aluminum ? Take everything off. Verify that the rail is in fact a 20 min rail. Then apply some blue loctite to the rail and receiver and remount it. Make sure to get it aligned fast because when that stuff sets up it is a bear to get it free. That way you are guaranteed the rail will not move under recoil. Weaver have never been very good rings in my opinion, so try some better rings like the steel Warne Maximas.
If this does not straighten things out, then your receiver and barrel are probably not in alignment.
Have you checked the total travel yet? I would like to know if you do indeed have 65 moa total travel. That would at least eliminate that question.
Thx I just looked at the old std height leopold mount and rings and the front base (2 pc) is about 1/8 inch shorter than the rear. I could visually see the weaver rail was shorter in the front so I thought all looked well. Not sure how much height difference it takes to make 20 MOA but wondering now if I have the real 20 MOA rail. Checked the scope and it has 58 MOA full travel.
Here is a pic of the old rings. I am hoping someone has a Winchester model 70 that can chime in on their base height.
Don't take me wrong, but are you sure that rail is 20moa? I have couple m70's so am familiar with them, and that rail just doesn't look like 20moa to me.
What is your load and velocity?
Not taking anything wrong. I just appreciate the help. I am wondering the same thing. Is your front mount shorter than the rear like my old one is in the picture? Are you using a 20MOA on yours? The boxes both said 20 and were purchased from the same dealer. These are my first 20 MOA rails as I am new to this so I wasn't sure. I just know that doing the math 58(full travel)-29+20-4(300zero) should give me roughly 45 and that is a far cry from 9.5 or 20.5.
I just emailed weaver so I am hoping they can give me measurements so I can mike it. If you have info specifically on the Model 70. I would love to hear it. Thanks again.
